Designing an Au/reduced graphene oxide modified carbon paste electrode for the electrochemical quantification of agnuside

This study reported a good linearity in the range of 0.050-250.0 nM and a low detection limit of 0.016 nM. The relative standard deviations (RSDs) for 10.0 nM and 100.0 nM of agnuside were obtained 3.3% and 1.2%, respectively. The sensor was successfully applied to determine agnuside in Vitex agnus castus fruit and urine sample.Graphical abstract
